Patent EP-0232094-A3 (EP)
Title: Chemical preparation of zirconium-aluminum-magnesium oxide composites
IPC: C04B35/44
Filed: 1987-01-23
Abstract: A composite ceramic material having improved properties is disclosed as well as several processes for preparing the same. The composite powder is substantially comprised of zirconia and spinel phases, produced by precipitation and calcination of the precipitate of the oxide forming precursor salts. A preferred process for introducing the zirconium is as a soluble and/or decomposable salt during precipitation of the spinel forming hydroxyl or halo hydroxyl spinel forming salts. The zirconium salt decomposes to zirconia during calcining and/or sintering of the powder resulting from the precipitation. A preferred composite is that obtained from magnesium and aluminum salts, resulting in a MgAl0<sub>4</sub> spinel and intimately admixed Zr0<sub>2</sub> which may contain a stabilizing agent.

Title: Method of esterifying dihydroxybenzenes
IPC: C07C67/08
Filed: 1987-07-08
Abstract: The present invention provides a method of esterifying dihydroxybenzene starting materials to synthesize unsymmetrical diesters in high yield. Many of the resultant unsymmetrical diesters are useful in dry bleaching compositions. The method can be practiced by selectively monoacylating a dihydroxybenzene starting material with an acid anhydride to form an intermediate monoester having the structure <CHEM> which is then acylated to form a diester reaction product having the structure <CHEM> wherein R1 is greater than R3 (and both R1 and R3 are alkyl groups) and X is a substituent group which does not participate in the esterification (or which can have a protecting group thereon).

Patent EP-0279278-A3 (EP)
Title: Frame for a supported flooring panel of sectional false floors, especially for corners
IPC: E04F15/024
Filed: 1988-02-03
Abstract: In frames consisting of sheet-metal sections (1) which have a bending edge at the edge with the tread plane because one leg (2) of the frame is bent round into the tread plane, this edge cannot be made sharp. Thus, when the panels are laid against one another, there is a small gap which, especially where thin hard floor coverings are concerned, can lead to a break of the floor covering at this point under a load exerted at a particular point. The sharp edge can be obtained, on the one hand, by designing the leg (2) as a sheet-metal part (5) bent back on itself, the free end of the sheet-metal part (5) coming to rest on the panel edge. Alternatively, it can be achieved in that a bead (9) formed in the sheet-metal section (7) in the vicinity of the respective panel edge is evened off in a tool in such a way that it forms as a result of the creep of the sheet-metal material. In the finished floor panel, the frame is filled with flowable hardening material. <IMAGE>

Title: Electroacoustic driving circuit
IPC: H04R3/00
Filed: 1989-04-19
Abstract: A driving apparatus for electrically driving a 
vibrator constituting an acoustic apparatus, wherein 
the output impedance of the driving apparatus is 
negative at at least one frequency associated with the 
output sound pressure of the acoustic apparatus among 
resonance frequencies when the acoustic apparatus is 
viewed from a terminal for driving the vibrator, and 
the ratio of the output impedance to the internal 
impedance inherent in the vibrator never becomes

the acoustic apparatus. Then, it is possible to 
eliminate mutual dependency between resonance systems 
having the resonance frequencies, design of the 
resonance systems become easy, and improved performance

Title: Device for applying an elastomeric filler on the bead core of a pneumatic tire
IPC: B29D30/48
Filed: 1989-06-01
Abstract: The described device comprises a bearing element (2) 
positioned to engage a bead core and subjected to the 
action of a friction wheel (7) acting in such a way as to 
make the bead core rotate around its own axis. Two pressure 
discs (17, 18) arranged specularly with respect to the 
lying median plane of the bead core act on opposite sides 
of a filler (34) to apply the same on the outer peripheral 
chafer of the bead core while this latter is rotating. The 
pressure discs lie according to respective planes convergent 
toward the bead core and divergent in the sense of rotation 
of the bead core to favour the release of the filler from 
the pressure discs. The pressure discs are thrust on 
the filler through a pneumatic cylinder (22) which exerts 
a constant force on an oscillating support (19) according 
to an axis parallel to the bead core axis and bearing the 
discs themselves.
